This Daiwa CN-103 Cross Needle Wattmeter is for watching some of my VHF & UHF transmitters. I bought this piece many years ago at a hamfest, and it had a broken SO-239 connector on the back. I thought it would be an easy chore to replace, but it became a major production. After some drilling of rivets in the RF sensor assembly, cutting and filing on the rear panel connections, and modifications to a standard SO-239... it was finally back in operation.
